Do you graze on Twitter on your iPhone while you’re watching Friday Night Lights? Do you post on Facebook from your Droid during American Idol finals? If so, you’re not alone.

According to a new study of smartphone users by media agency Initiative, 60% of mobile web usage is taking place at home, while people are watching TV, listening to the radio or right before the nod off to sleep.

Nearly a third of smartphone users start their day connecting to the internet on their mobile device and 45% end their day that way.
